Description

Technical Field

[0001] This utility model relates to agricultural tillage machinery, specifically a plow-rotor integrated machine. Background Technology

[0002] For easily compacted fields (such as saline-alkali farmland with high salt content and simple, easily compacted soil structure), traditional plows cannot fully break up deep soil clods, while rotary tillage is difficult to reach deep layers. Therefore, a device that can reach deep layers and effectively crush compacted soil clods is needed. Chinese utility model patent CN221151934U discloses a plow-rotor integrated machine, including a frame. A crushing mechanism is installed on the frame behind each plowshare. The crushing mechanism includes a rotary cutter mechanism, whose rotation shaft is driven by a belt. A belt tensioner is also required, making the entire transmission system complex. Furthermore, the rotary cutter equipment cannot be disassembled and cannot be used as a standalone plow. Moreover, the depth limit wheel uses a traditional hand-cranked screw for height adjustment, which is prone to self-rotation during prolonged bumpy operation, causing changes in the depth limit. Additionally, the current plow-rotor integrated machine has a simple tractor mounting structure, making it inflexible in use. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a plow-rotor integrated machine with a simple transmission structure and a detachable rotary blade system.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A plow-rotor integrated machine includes a frame on which a plurality of plows are mounted, and a vertical rotary cutter is mounted behind each plow. A depth-limiting wheel is mounted on one side of the frame. A transmission system is mounted on the frame, the transmission system including a first drive shaft, a commutator, a second drive shaft, and a power distribution shaft. The rear end of the first drive shaft is connected to the input end of the commutator via a universal joint. The two ends of the second drive shaft are respectively connected to the commutator and the power distribution shaft. The power distribution shaft is driven by the rotating shaft of the rotary cutter via a gear set.

[0006] Furthermore, the housing of the power distribution shaft is fixedly connected to the frame via a connecting rod, and a reinforcing plate is provided between the connecting rod and the frame.

[0007] Furthermore, the connecting rod is detachably connected to the frame by bolts; the top of the reinforcing plate is detachably connected to the connecting rod by bolts.

[0008] Furthermore, the front end of the frame is provided with an upper hanging part and a lower hanging part, and the lower hanging part includes two ear plates arranged symmetrically on the left and right.

[0009] Furthermore, the lower hanging part also includes two hanging shafts arranged on the left and right sides.

[0010] Furthermore, the depth limiting wheel includes a vertical rod fixed on the frame and a sleeve that is fitted on the vertical rod and can slide up and down. A locking bolt is provided between the vertical rod and the sleeve. The wheel body of the depth limiting wheel is fixed on the sleeve through a rotating shaft.

[0011] Furthermore, the vertical rod is provided with several threaded holes, and the sleeve is provided with a through hole corresponding to the threaded holes.

[0012] Furthermore, the front end of the first drive shaft is provided with a universal joint that connects to the power output end of the tractor.

[0013] Furthermore, the depth-limiting wheel includes an inflatable tire or a metal rim.

[0014] The beneficial effects of this utility model are:

[0015] Its transmission system employs a simple and detachable structure using a drive shaft, universal joint, and gear reversing, allowing the rotary cutter power system to be removed and used as a standalone ploughing machine. The improved design of the depth-limiting wheel avoids the problem of depth variations caused by the traditional hand-cranked screw during bumpy operations. Two sets of mounting brackets connect the front of the frame to the tractor, offering high installation flexibility. Attached Figure Description
